bridgesampling: An R Package for Estimating Normalizing Constants

open access: yesJournal of Statistical Software, 2020
Statistical procedures such as Bayes factor model selection and Bayesian model averaging require the computation of normalizing constants (e.g., marginal likelihoods).

Optional Stopping with Bayes Factors: a categorization and extension of folklore results, with an application to invariant situations [PDF]

open access: yes, 2020
It is often claimed that Bayesian methods, in particular Bayes factor methods for hypothesis testing, can deal with optional stopping. We first give an overview, using elementary probability theory, of three different mathematical meanings that various ...

SHAR and effective SIR models: from dengue fever toy models to a COVID-19 fully parametrized SHARUCD framework

open access: yesCommunication in Biomathematical Sciences, 2020
We review basic models of severe/hospitalized and mild/asymptomatic infection spreading (with classes of susceptibles S, hopsitalized H, asymptomatic A and recovered R, hence SHAR-models) and develop the notion of comparing different models on the same ...

Make the most of your samples : Bayes factor estimators for high-dimensional models of sequence evolution [PDF]

open access: yes, 2013
Background: Accurate model comparison requires extensive computation times, especially for parameter-rich models of sequence evolution. In the Bayesian framework, model selection is typically performed through the evaluation of a Bayes factor, the ratio ...

Empirical Bayes Matrix Factorization

open access: yesJournal of machine learning research : JMLR, 2018
Matrix factorization methods - including Factor analysis (FA), and Principal Components Analysis (PCA) - are widely used for inferring and summarizing structure in multivariate data. Many matrix factorization methods exist, corresponding to different assumptions on the elements of the underlying matrix factors.

The bridge between design and analysis

open access: yesPerspectives on Medical Education, 2017
The overall purpose of the ‘Statistical Points and Pitfalls’ series is to help readers and researchers alike increase awareness of how to use statistics and why/how we fall into inappropriate choices or interpretations. We hope to help readers understand

Comparison of Naive Bayes Method and Certainty Factor for Diagnosis of Preeclampsia

open access: yesLontar Komputer, 2022
Preeclampsia is a disease often suffered by pregnant women caused by several factors such as a history of heredity, blood pressure, urine protein, and diabetes. The data sample used in this study is data on pregnant women in the 2020 time period recorded

Application of Bayesian Analysis in Medical Diagnosis

open access: yesJournal of the Practice of Cardiovascular Sciences, 2019
In this work, we outlined the application of the Bayesian technique for integrating the results of multiple tests while treating any disease. We provided an overview of the fundamental concept of Bayesian analysis in making an inference about a ...

From p-Values to Posterior Probabilities of Null Hypotheses

open access: yesEntropy, 2023
Minimum Bayes factors are commonly used to transform two-sided p-values to lower bounds on the posterior probability of the null hypothesis, in particular the bound −e·p·log(p).
